Warmer temperatures in Iowa are expected to bring mostly rain to the state. Right now, an 80 percent chance of precipitation is forecast.

Temperatures overnight are expected to stay in the 30s.

By Thursday morning, the chance for rain drops to 30 percent.

A more significant system moves from the Rockies into the plains for the weekend.

Precipitation types will vary as the weekend storm moves through, but the most likely areas for significant snow and travel problems appear to be from Nebraska into southeast South Dakota and Minnesota, possibly brushing northwest Iowa.

In Iowa on Saturday night, rain possibly mixed with snow is expected as temperatures drop into the lower 30s. Rain is expected to continue into Sunday.
